Specification forming part of Letters PatentiNo. 184,785, dated November 28, 1876 application tiled E' Detemter 27j, 1375. Y

To all whom it may concwuV and useful Improvements in Grain-Separators;

and I do hereby declare that the following is a full, clear,vandrexact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had-to theaccompanying drawings, and to letters vof referenceA marked thereon, which form a part of this specification.

Ilhe object of the invention is to simplify the construction Of the machine, to increase its efficiency, and at the same time reduce its cost of manufacture; and to this end the invention consists in a novel construction and arrangement of parts, as will be hereinafter fully set forth.

Figure l is a side elevation, and Fig. 2 is a vertical longitudinal section. Fig. 3 is a vertical longitudinal section, showing another method of hanging and actuating the sieves of the Winnower; and Fig. 4 is a plan View of the carrying-apron, showing its construction and arrangement relative to its driving and supporting mechanism. u y

A is the top of the machine 5 A1, posts, and A2 a girt; but as the frame, the cylinder H, and concave I may be of any usual or approved construction, they need not be specically described. B is the side or casing at both sides of the machine. C G1 are disks or circular metallic plates, arranged in apertures cut for their reception in each side of the casing B, and mounted upon shafts c, which are supported upon or in bearings C2, secure-d to the frame, orv formed partially or wholly in the frame. D represents a carrying and separating platform, consisting of a series of parallel bars provided with fingers d. These bars are attached to the upper portion of each of the disks C C1, as indicated at 01 c1, Fig. 2, by means of rods or wrist-pins, which can turn in the bars. D' (see Fig. l) are connecting-rods or links attached to disks C (l1 outside of the frame. F is a crank-wheel mountedon a shaft, f, and connected with either link D', or one of the disks, by means of a Y pitman,f. E ELE2 represent, respectively',

Be it knownrthat I, JOSEPH KooNs, of` Stillwater, in the county of Viashingtonand vState of Minnesota, have invented certain new the side, riddles, and fan of a winnower. The riddles or sieves and their inclosing case or sides, are supported at the rear or dischargingend upon thependulum-links ,or pivoted arms e, and at the front orl receiving lend upon the disks O1, asV indicated at el. The upper end of each'linke may be mounted in a horizontal slot, e2.` v,(,See FigsLZand 3.) K is the discharging spout .of the shoe of the winnower. As any of the improved kinds ofwinnowers which are adapted for the purpose may be employed, no more detailed description of its various parts need be given. G is a grain-table. Gr' is a raddle-belt or carrier, traversing the upper surface of grain-table G. The raddle-belt is operated by means of a driving-pulley, F', or shaft f, at each side of the machine, and supporting or tension pulleys g2, as is customary in this class of machine.

The grain is fed in at and between the thrashing-cylinder H and the concave I, from whence the mingled mass of grain and straw is discharged upon the separator and carrier D, Where it is thoroughly agitated, the grain falling between the bars upon either the graintable G and raddle belt G', or the winnower. As the raddle belt traverses the grain-table, (in the direction indicated by the arrow in Fig. 2,) it collects the grain and delivers it to the sieves, as will be readily understood.

In Fig. 3 I have shown another construction of devices for actuating the sieves or riddles ofthe winnower, in which L is a segmental brace or carrier, attached to the upper edge of each side of the rear part-that is, the shaking part, in which the sieves are supported. l-is a slot in segment L, and c2 is a pin projecting from the face of circular head C1, and entering the slot l, both ends of the shaker being mounted upon vibrating links e. As the head G1 oscillates upon its shaft c, the required shaking motion is imparted to the sieves; and, by moving pin c2 farther from or nearer to the shaft c, the extent ofthe shake or throw of the sieves may be varied.

Although the shoe of the winnower is actuing movement of said shoeis regulated by the position of the links e independently of the oscillating motion of the heads, so that these two motions-that is, the length of thevrecip-M y rocation andthe amount of the rise and fall, or toss, as it is sometimes calledmay be adjusted or determined independently ofeach other. f

C3, in Fig. 3, are anged pulleys secured to a driving-shaft at the lower end of the carry ing belt or apron, orraddlelbelt' G', tov operate said belt, the upper end of the belt being sup. ported by means of aiiged pulleys C2, mounted loosely upon shaft c, or upon a `shaft provided for the purpose; or, when preferred, the belt may be driven from a shaft at the upper end, as convenience or economy of construction may indicate. The `slats g1 on belt or apron G project beyond theedge of the apron, and traverse a rib, g, (see Figs. 3

and 4,) axed to the side 'of the machine, Athus supporting the central` portion of said apron. When preferred, rollers extending the entire width of the belt may be employed instead of the pulleys G2. It will, of course, be

understood that there is to be a segment-carrier, L, and pin c2 at each side of the win-` nower. i

y Y From an examination of the drawing it will be seen that the separating and carrying platform, the winnower, and the raddle-belt 4are all operated from the single shaft f.

What I claim is- 1. The combination, with the shoe of the Winnower, of the segment or carrier L, the 1 circular head G1, and pin c2, substantially as set forth.

1 2. The combination of the separatin g table or platform D, the' disks C1, and the shoe of the winnower, provided with the arcs or braces L,4 substantially as set forth.

8. The combination ofthecircular heads C1, their shaft c, the raddle-belt G', supported at its upper end upon loose pulleys G2 on sb aft c1, the separating-platform D, and the winnower, these partsbeing constructed and arranged substantially as set forth.

In testimony that I claim the foregoing as my own I afx my signature in presence of two witnesses.`
